Im trying to understand pointers & linked lists, so far so good, but there is one thing i cant get my head around.
I created a Linked list of a struct, witch contains just an int x and *next ofcourse. I make 4 structs in the list, and now im trying to delete the first in the list.
(Number is the struct and Head is pointing to the start of the list.)
1 2 3
Current=Head; //Current points to the same thing Head is pointing to.
Current=Head->Next; //Why does this line make Head pointing to the next in the list!? Is it a law that Current=Head & Head = Current now? o_O
And another thing, tried to make the samething with something i find to be logical.
1 2 3
These lines delete the last in the list of my 4 structs, Im Conpuzzled.
Thanks in advance! :)
Im starting to think that my tutorial aint that good.. http://www.functionx.com/cpp/articles/linkedlist.htm
To delete the first of the list, i need head pointing to the 2nd element, so the first one is no longer in the list, am i right?
Could someone please maybe give me a good link on this topic?
Nevermind that, got my head around it, but i have a new question. The line below, they work just fine, but i cant understand why.. Could someone, please, explain? I even tried to write on paper, but still could not understand whats going on here :|
1 2 3 4 5 6 7 8 9
Number *Retrieve(int Position)
for(int i=Count()-1; i>Position && Current!=NULL; i--)
